As part of our ‘What’s the Matter?’ mini-topic, we have been studying the water cycle.
We recreated the elements of the water cycle by pouring water (with blue food colouring for the sea!) into a zip lock bag and placing it in a warm area of the classroom.
Measuring skills were used.
We watched the water evaporate .
At the top of the bag, small water droplets formed to show condensation.
And finally, the water vapour got heavy and trickled down back into the ‘sea’ just like precipitation.
A simple yet effective way of showing this process.
